Intriguingly, BTInternet blocked Lostpedia, so I could not follow the link cited by Nanker Phelge. Wikipedia however gives the rather sick game away.
Incidentally, although the story is fictitious, surely a plane from Sydney to Los Angeles would hardly be lost in the so-called 'Bermuda Triangle' (real location, mythical claims)? If it would have to way off-course to be anywhere near The Bahamas!
